GEORGE A. BEACH, OF CHICAGO, ILLINOIS, ASSIGNOR TO EDWIN E. \VISE, OFSAME PLACE.

STREET-CAR WARMER.

SPECIFICATION forming part of Letters Patent No. 390,154 dated September25, 1888.

Application filed October 14, 1887. Serial No. 252,330.

To all whom it may concern:

Be it known that I, GEORGE A. BEACH, a citizen of the United States,residing in Ohicago, in the county of Cook and State of Illinois, haveinvented a new and useful Improvement in Street-Oar Warmers, of whichthe following is a specification.

My invention relates to devices forwarming street-cars.

The object of my invention is to provide an efficient and practicalmeans, of a simple,cheap, and durable construction, for warmingstreetcars, which will heat the ears uniformly from end to end, offer noobstruction to getting on or off or through the cars when the same arecrowded, and which will not diminish or interfere with the seating orcarrying capacity of the cars.

To this end my invention consistsin a streetcar furnished with its usualfloor or bottom, a

perforated or open floor above the same with a space between, and athird or non-conducting floor or bottom with a space between it and thecar-floor, the car-floor being furnished with a central opening orsocket to receive and support the soapstoneheater holder. Thesoapstone-holder consists of a cast-iron box or receptacle, having sideand bottom ledges to support the heater-stone and leave a space for 0the circulation of air between the stone and the bottom and side wallsofthe holder. The holder has a horizontallyprojecting flange, which restsin the socket or rabbeted edge of the car-floor surrounding the openingformed 5 therein. The heater-stone holder has a vertical wall inside itsmarginal inclined wall, and through this vertical wall a series ofopenings are provided for the passage of the hot air from the stone upthrough the car. The bottom of the stone-holder is also furnished with acentral opening for the admission of the air to the heater. Openings forthe passage of air are provided through the vertical wall of thecar-seats, near the bottom thereof, and also down between the backof theseats and the outer wall of the car, which openings communicate withopenings for the passage of air through the car floor, thus leading theair into the space between the lower or non-conducting floor. Fresh airis led from outside airinjectors, at the top of the car, down through(No model.)

tubes which communicate with the air-space between the car-floor and thelower non-conducting fioor. The openings through the carfioor, whichlead the air from the interior of the car down to the heater, areprovided wit-h valves or dampers operated by a rod extendinghorizontally through the car under the seats and projecting through tothe platform, so that the driver or conductor may close or regulate thesame when desired. By closing these valves or dampers fresh air onlyfrom the outside of the car will be supplied to the heater. The freshairpipesare also supplied with valves or dampers, so that they may be 6closed or partially closed when desired, thus enabling the temperatureof the car to be governed as desired. The perforated or slatted floorabove the car-floor and the heater is made removable, or with removablesections, through which the soapstone heaters are lifted out at the endof each trip and replaced by hot stones taken from the heating-furnaee.The size and number of theheater-stones and heater-holders may be variedas desired, according 75 to the size of the car and the length of thetrip.

In the accompanying drawings,wl1ich form a part of this specification,and in which similar letters of reference indicate like parts, Figure 1is a vertical cross-section of a device embodying my invention. Fig. 2is a detail perspective view of one of the heaterstone holders. Fig. 3is a plan view looking down from a point within the car, and made on asmaller scale. Fig. 4 is a partial vertical see- 8 5 tion on line 4 4 ofFig. l, and Fig. 5 is a vertical sectional view showing one of theairinjectors at the roof of the car. Fig. 6 isa plan view of theheater-block, and Fig. 7 a perspective view of a lifting tool orimplement. c

In the drawings, A' represents a street-car, which may be of any usualor ordinary construction. The car which, for convenience, I have shownin the drawings, represents a form of cable car having a grip platformor space 5 at one end of the car and an exit and entrance platform atthe other end of the car.

A represents the car-floor; A A the outer side walls of the car; A, thecal-door; and At the seats of the car.

B is the heater-block, preferably made of soapstone, and 0 is theheater-stone holder,

IOO

preferably made of castiron and having a horizontal supporting'tlange,c, which rests in a suitable recess or opening, a, cut in the ear-floorA. The edges of the ear-floor around this opening a are rabbeted, asshown at a, so

that the flange of the stone-holder may fit flush with the upper surfaceof the ear-floor. The heater-stone holder is furnished with a verticalor upwardly-projecting wall, 0, inside the outer inclined wall of theholder, from which vertical-wall 0 project horizontal and verticalledges 0 upon which the heater-stone rests, so as to leave an air-spacebetween the stone and the bottom and vertical wall a of the holder. Thebottom of the holder is provided with a central opening, 0, for theadmission of cool air to the stone, and the vertical wall 0' isfurnished with a series of openings, 0, cut therein for the passage ofthe hot air out laterally from the under side of the heater-stone.

The inclined or flaring walls of the stone-- holder 0 deflect the hotair upward as it issues laterally from the openings 0.

D is the lower or noncondncting floor of the car, secured at itsmarginal or side edges to the car-floor A and supported thereby. Thissupplemental floor or bottom preferably consists of sheet metal linedwith a sheet of mineral wool, asbestos, or other non-conductor, d. Thissupplemental non-conducting floor D atfords a close air space, D, belowthe ear-floor A and surrounding the stoneheater holder 0.

The noirconducting floorD may, if desired, be made to extend the fulllength of the car;

u but it is preferable and cheaper only to extend this supplementalfloor the length of the stoneholder G; and I ordinarily provide theear-floor on its under side with downwardly-projecting cross-bars ofwood, d, to which the bottom D is secured at its ends. One of thesebottoms or floors D is provided for each of the heaterstones B andheater-holders 0.

As shown in the drawings, the ear is furnished with three heater-stonesand heaterholders. The car-floor A is provided with openings a under theseats A,which leadinto the air-space D, between the supplemental floorsD and the car-floor A. The air is conducted from the interior of the carinto the space a beneath the seats through openings a" formed in thevertical walls A of the seats near the bottom thereof and just above theupper removable perforated floor, F, of the car. Air from the topportion of the ear is also conducted down to and circulated around theheater-stone through air-passages a at the back of the seats, or betweenthe back of the seats and the side wall of the car. Fresh air from theoutside of the ear is also conducted down to the heater-stone from theair-injectors G at the top of the car through the vertical air-pipes 9,horizontal air-pipes g, which extend longitudinally of the car under theseats, and the branch pipes g, the ends or months of which lead into theainpassages c in the earfloor A. The openings at in the floor A may beall closed simultaneously by valves or dampers H, which are operated bya rod, h, extend ing longitudinally of the car under the seats andprojecting through the front end wall of the car. Each of the valves His connected to this red by a bent lever, 7L, and link h. The fresh-airpipes g are furnished with valves or dampers g", the handles of whichproject through the front end wall of the car, so as to be accessible tothe driver or conductor on the outside. The upper perforated floor, F,is preferably made of open slat-wo1'l ,and is supported upon suitablelugs or risers. f,between the same and the car-floor A. The centralportion, f,of this slatted or perforated floor F is made solid or closedand lined with zinc f on its under side, so as to prevent the heat fromthe stone risi ng directly upwardand to deflect the hot air outlaterally through the open ings in the perforated floor F. The centralzinc-lined portion,f, ofthe upper floor should be made somewhat largerin size than the stone beneath, and is made removable, so that by simplyremoving or opening this portion fof 9o thetloor F the heaterstone maybe removed and replaced by another. The part f is preferably hinged atone of its edges to the perforated floor F. The heater-stones B are eachfurnished with one or more cavities, devices, or projections, 1),preferably consisting of simple cavities or notches cut in the face oredges of the stone, and by means of which the stone may be readilygrasped and carried with suitable lifting tools or deviees,b,for thispurpose.

At the end of each trip,or when cool,thehcaterstones B are lifted out oftheir holders, placed in the furnace to be heated, and the holdersrefilled with other hot stones taken from the furnace.
